I was a big fan of Cokin in the past too. But eventually, I have tried to avoid it whenever possible. The biggest problem is they could be scratched too easily. You cannot employ the regular cleaning routine to wipe them with lens tissue or anything at all. The only safe way is to wash them with detergent. Another problem is they are far from flare resistance because they are uncoated resin (soft plastic). To deal with different sizes of filters, I now use any array of step-up rings. For instance, the biggest filter size of my lenses is 67mm. I just bought all filters in that size, and then put step-up rings on other lenses. These include 49->67mm, 58->67mm etc. The downside is I cannot use the original lens hood. But over the years, I have bought a few "often-use" filters just for these lenses (like PL and skylight etc) so this is not a huge problem as I once imagined. However, you have to determine what the biggest filter size you will ever need. regards, Alan Chan _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp - This message is from the Pentax-Discuss Mail List.
